Sun melon, or kharbuja, is a type of musk melon with a rough, netted, yellowish-brown rind. The flesh inside is a vibrant orange or peach color, with a soft, watery texture and a very sweet, musky flavor. It's a quintessential summer fruit in India, known for its high water content, which makes it a perfect choice for staying hydrated during the hot weather. It's often eaten fresh or blended into juices.
